What is seffaf-plak.com?
seffaf-plak.com is an Invisalign-focused information and decision guide prepared for patients researching clear aligner treatment and their families. Our aim is to answer questions such as 'what are clear aligners', 'who are they suitable for', 'how long does treatment take' and 'what determines the fee' clearly, without exaggeration and in line with scientific consensus. At our clinic, clear aligner treatment is provided with the Invisalign system; our content explains this system and the treatment process with concrete criteria. Rather than offering a diagnosis or treatment recommendation, the content aims to help you prepare for the topics you will discuss with your doctor at the examination. You can use the site to learn what to expect before starting treatment and to ask your doctor the right questions.
What are our content principles?
- Measured language: No superiority claims are made for any treatment or system; information is given with concrete criteria.
- Regulatory compliance: In line with the rules on the promotion of healthcare services in Turkey, no price figures, before-and-after patient photos, patient reviews, superiority claims or statements promising results are used.
- Medical accuracy: Information is kept consistent with the Turkish Orthodontic Society, the Turkish Dental Association, the American Association of Orthodontists (AAO) and peer-reviewed publications. Values such as daily wear time, aligner change intervals and treatment duration are given as generally accepted ranges.
- No diagnosis: No page makes a decision about your case. Suitability, duration and method are evaluated only at an examination.
- Plain language: Technical terms are explained in parentheses where they first appear; short sentences and concrete lists are preferred.
Who publishes the site?
The site is published by Funda Sarıkaya Oral and Dental Health Polyclinic in Çankaya, Ankara. The clinic is located at Park Oran Ofis, Kudüs Caddesi, Oran, and is open Monday–Saturday from 09:00–20:00. At the clinic, clear aligner treatment is provided with the Invisalign system. If you are curious about the clinic process, see the clear aligner treatment in Ankara page.
What pages does the site consist of?
The content is organized into five groups. The 'Clear aligners' group covers the basics (what they are, the treatment process, duration, use, cleaning, problems, retention). The 'Decision' group addresses the factors that determine the fee, the state hospital option, the comparison with braces, age groups and suitability. The 'Conditions' group explains medical conditions such as crowding, gaps between teeth, open bite, deep bite and crossbite one by one. The 'Information Center' group contains frequently asked questions, a glossary, videos, sources and the Ankara clinic page. The 'About' group consists of this page and the contact page. Each page answers the main question directly in the first paragraph and links to related pages.
Which sources do we use?
The institutions and publications we refer to in our content are listed on the sources page. Our main sources are the patient information materials of the Turkish Orthodontic Society and the Turkish Dental Association, the AAO's patient resources, the oral and dental health publications of the Republic of Türkiye Ministry of Health, Cochrane Oral Health reviews and the official patient pages of aligner manufacturers. Manufacturer sources are used only for product features; claims of effectiveness are compared against independent publications.
How often is the content updated?
Pages are updated at least once a year, and also whenever a new regulation, an association recommendation or an important scientific publication appears. If you notice an error or omission on a page, you can reach us through the channels on the contact page; reports are assessed by the doctor. A clear aligner glossary has been prepared for short definitions of the terms used on the site, and an FAQ page for frequently asked questions.
